Just bought a house last June. The garage was converted into a office. My goal over next year or so is to convert it into a home theatre room. Its a 20x20 and the ceiling is 8'7". There is 4 columns in the center of each wall. Two of them are load bearing walls. There is a door in-between 1/3 of the south wall. I was thinking on putting in 7 theater seats and maybe a bar but not sure. I will try to put some picks up next week sometime to show what I'm writing about thanks.
